MACHINE FOR SOLDERiNG BAlL-EARS ON BODIES OF CANS OR OTHER VESSELS.

SPECIFICATION forming part of Letters Patent No. 681,000, dated August20, 1901.

Application filed October 22,1900. Serial No. 33,927. (No model.)

Be it known that I, HORATIO N. NORTON, a

citizen of the United States, residing in Maywood, in the county of Cookand State of Illinois, have invented a new and useful Improveinent inMachines for Soldering Bail- Ears on Bodies of Cans or other Vessels, of

which the following is a specification.

upon which the bail-ears are to be soldered,

ineans of which bail-ears may be rapidly and cheaply soldered in place;and it consists in the combination, with a movable table or carrierprovided with a series of blank-holders for holding the flat sheet-metalbody-blanks of a series of ear clamping or holding rods mounted on thecarrier, a stationary cam on track for raising and lowering theear-clamping rods, a series of rotary annular soldering" tools or ironsmounted on the carrier, a stationary cain or track for raising andlowering said soldering-tools, gears for rotating said tools, burnersfor heating the soldering-tools,

and cooling devices for cooling the soldered seams uniting the bail-earsto the flat bod yblanks.

It also consists in the novel construction of i i parts and devices andin the novel combinations of parts and devices herein shown anddescribed, and specified in the claims.

In the accompanying drawings, forming a part of this specification,Figure l is a side elevation of a bail-ear-soldering machine embodyingthe invention. Fig. 2 is a plan view. Fig. 3 is a central verticalsection, and Fig. 4

is a detail view of the blank holder and carrier.

In the drawings, 11 represents the frame of the machine, the samepreferably comprising an upright standard or shaft.

12 is a rotary carrier or table journaled to I turn on the shaft orstandard 11, furnished.

with a series ofbody-blank holders, each preferably consisting of a pairof angle-pieces To all whom, it mar concern:

adjustably secured to the carrier or table 12 by set-screws 14 andadapted to receive the flat body-blank 15 between them and hold the samein proper registry with the solderingtools while the bail-ears 16 arebeing soldered to the blank 15. The rotary table 12 is provided with anupright ring 17, upon which are secured a series of brackets or bearings18, in which are mounted or journaled the hollow shafts 19 of therotarysoldering-tools 20. Each of the hollow shafts 19 is furnished witha collar 21, which engages an inclined circular track or cam 22, whichthus serves to autorna ticall y raise the solderin g-tool, as requiredas the carrier or table-12 turns or travels around. Inside each of thehollow shafts or sleeves 19 of the annular soldering-tools 20 is an earholding or clamping rod 23, having 'a rounded end 24, which enters theeye or central hole of the bail-ear, and thus centers and holds thebail-ear in position while the rotary soldering-tool is operating uponthe same to melt the ribbon-solder with which the edge of the bail-earis hemmed before the body-blank and bail-ears are put in the machine.Each of the clamping or ear-holding rods 23 is furnished with a collar25, which rides upon an inclined track or cam 26, secured to thestationary frame of the machine and by which the ear-holding rod islifted, as required, at intervals to enable the can-body blanks andbail-ears to be placed in the machine and the same to be removedtherefrom after the ears have been soldered in place. The rotating table12 is further provided with a heater-ring 27, having an annular chamber28, into which the soldering-tools are withdrawn when the same arelifted by its. operating-cam 22. This heating-chamber is heated by aseries of gas-burners 29, each of which is preferably furnished with anair-pipe 34, entering the gas-pipe 32, and the burner or gas-nozzleprojecting slightly upward into the annular heating-chamber 28 andoperating to project the flame against the soldering-tools as theytravel around. a i

31 is an annular gas-supply pipe having branches 32 leading to each ofthe burners, and 33 is an annular air-supply pipe having jectingorificesor nozzles.

35 is the gassfeed pipe, and 36 the air-blast- 4 feed pipe.

Secured to the upper end of the shaft or standard 11 is a stationary ornon-revolving gear or toothed wheel 37, the teeth of which mesh withgears 38 on the hollow shafts 19 of the soldering-tools,th us causingthe solderingtools to be rotated as the carrier 12 revolves. The carrier12 itself is rotated, as required, from the driving-shaft 39 through theworm 40 thereon, meshing with the worm-gear 41 on the rotary table orcarrier 12.

After the soldering has been properly done by the operation of thesoldering-tool the soldered seam is cooled, so as to set the solder, bya series of air-nozzles 42, connected to the air-blast pipe 43.

In operation the flat'body-blank of the sheet- 1 metal can, pail, orother vessel is placed in I the holder 13 on the carrier 12, and thenthe two bail-ears 16 16, which are to be soldered to it, are put inposition in the annular countersin k, with which the bod y-blank isprovided for this purpose, this being done at the high portion of thecam or tracks 22 and 26. As the carrier 12 revolves on its upright shaftthe cam-clamping rod 23 is permitted by its cam 26 to move down upon thebail-ear by its own weight, and after the bail-ear is thus clamped orcentered in position the rotary,

soldering-tool 20 is lowered into position for operation by the cam 22and rotates in c011- tact with the seam to be soldered. After the solderhas been thoroughly fused and distributed or worked into the seam by therotary action of the soldering-tool the inclined cam or track 22 liftsthe soldering-tool from the work and the further movement of the carrier12 conveys the work into position to be operated upon by thecooling-nozzles,which serve to set the solder so that the Work may beremoved from the machine when the carrier 12 conveys it around to therequired position.

I claim- 1. In a machine for soldering bail-ears upon body-blanks ofsheet-metal cans, pails or vessels,'the combination with a rotary tableor carrier furnished with a series of body-blank holders, and a seriesof rotating solderingtools mounted on said table, substantially asspecified.
